Autisa?

[motovespa]

After pulling the barrel off my spanish primmy I was quite chuffed to find it was an Autisa kit and not a standard barrel.

Does anyone have any info on these?

It's an alloy barrel with an iron liner, the piston has two rings, the top one being very close to the top of the piston (Does that make it high compression?) - It looks to me like a 75cc barrel or somewhere in that ballpark, definetely much smaller than a 125 barrel.

The only thing I've found on the net about them is they were made in Spain during the 80's.

Cheers,

My Primmy is a Spanish 75cc one so wouldn't have had a 125cc barrel as standard.

The Autisa barrel is 100% not a 125cc barrel, after doing a bit of searching on the yahoo smallframe group, it looks like it might be a 105cc kit. They reckon it's one of the best kits to put on the really early smallframes where you can't easily fit a 125cc barrel on it.

I did a quick measurement of the piston and it looked like 51mm (although I'm not 100% if I measured it correctly!)
